Why is that even an issue?

Build a electric car which needs less components, less repair and can actually be refuelled at home.

In worst case, put a range extender into it. Doesn't cost much and just burns fuel as before.

The only risk could be that batterie technology just suddenly stops. But i would argue that its quite a save bet.

And it doesn't has to do anything with saving the environment.

There is obvious a technolgy change happening. It might be unclear how long it still takes or if global warming hits us quicker but sitll.
